Kaiga Atomic Power Project (Unit 1 & 2)
Powering The Nation
With Nuclear Energy
L
&T began its journey in to construction of
Nuclear power projects in a modest way, by
undertaking the construction of office facilities for
the Atomic Energy Establishment and laboratories
for Bhabha Atomic Research Centre at Trombay
during mid 60s. The construction of Main plant
civil works at Kalpakkam for the 220 MWe Madras
Atomic Power Project Unit 1&2 during 70s was
the first major project in the nuclear segment.
Subsequently, the Main plant civil works for the
220 MWe Kaiga Nuclear Power Project (Unit 1&2)
in Karnataka was executed by L&T. Erection of
almost all heavy water plants in India are executed
by L&T.
Realising the vast potential and business
opportunities in this segment the Nuclear Business
Unit was formed by L&T in the year 1999-2000
when it secured the 540 MWe Tarapur Atomic
Power Project, Unit 3&4. It should be mentioned
that Tarapur Atomic Power Project was one of the
major projects for L&T, where different business
units of L&T were actively involved in the execution
of the project - Nuclear, Electrical & Instrumentation
BUs of ECC Division; Heavy Engineering Division;
Nuclear BU of E&C Division to name a few.
Achievements
Some of the notable achievements in Nuclear
segment include:
• Out of the total installed capacity of 7280 MWe
of nuclear power (both commissioned and
ongoing); L&T is involved in almost all Nuclear
power projects in the country extending up to
5280 MW.
• Successful completion of main plant civil works
of 2x540 MWe Tarapur Nuclear Power project
in a record 60 months from the first pour of
concrete is considered as a great achievement
- One among the six reactors in the world to
achieve this feat.
• Successful completion of Primary Piping
Package (the heart of the nuclear plant) on
time including other mechanical packages in
the Country’s maiden 2 x 540 MWe Tarapur
Nuclear Power Project. This helped L&T in
understanding the criticality, stringent quality
requirements, etc and as a sequel, it secured
major mechanical packages in Kudankulam
Nuclear Power Project 1&2.
L&T is involved in the execution of India’s first
2x1000 MWe Nuclear Power Project at Kudankulam,
which is one of the most prestigious projects
undertaken by Government of India in collaboration
with Russian Government. Initially, L&T’s
participation in civil works involves construction
of infrastructure facilities and auxillary buildings
only. However, the scenario changed, when L&T
secured four major mechanical packages which
involve technology certifications, being done for
the first time in India, etc.
This apart, auxiliary systems such as Induced Draft
Cooling Towers, HVAC, Service Water Systems,
etc are being constructed on EPC basis.
L&T is also involved in many Reactor back end
projects, that is construction of fuel reprocessing
related facilities such as Additional Waste Tank
Farm, Spent fuel Storage Facilities, Power Reactor
Fuel Reprocessing facilities, etc at various locations
in India. Thus, making L&T an all rounder when it
comes to execution of almost the entire spectrum
of activities involved in the construction of nuclear
power projects.
On the whole L&T is playing a critical and significant
role in the India’s Nuclear Power sector.

L&T’s Track Record
in Nuclear Power
N
uclear power projects are considered as
one of the sustainable energy projects of the
future. The Nuclear Power Corporation of India
Limited (NPCIL) presently operates 17 nuclear
power plants in the country at different locations.
India has made a strong beginning in the field of
Nuclear Power. Today it is quite self–sufficient
from technology and resources point of view and
NPCIL has ambitious plans of achieving 20,000
MW by 2020, improving from the current installed
capacity of 4120 MW.
Over the past five decades, ECC has constructed
many nuclear-related structures and played
a major role in this sector. It has the capability
to construct critical and complex structures for
Nuclear Power generation. ECC has the distinction
of making constructive contribution to almost all
the Nuclear power plants in the country. Some of
the important projects are Madras Atomic Power
Project, Kaiga Atomic Power Project, Tarapur
Atomic Power Project, Rajasthan Atomic Power
Project and Kudankulam Nuclear Power Project.
ECC has also been involved in other nuclear
field related projects such as heavy water plants,
nuclear waste management, rare materials project,
• Vol. No. 31 • Issue No. 4

etc falling under the purview of DAE/ BARC. In
fact, ECC’s association with DAE started in the
early 60s, when it was awarded with design and
construction works for radiological and modular
laboratories at Trombay.
ECC’s major involvement in nuclear power projects
started at MAPP in 1970 when it was entrusted with
the construction of the reactor and turbine buildings
for MAPP. The contract for civil construction
included the reactor building with 40m high and
45m dia structure topped by a dome, sub-structure
for service building, cooling water system and
outfall structure, demineralisation plant, central
stores, PHT purification buildings, Fast breeder
test reactor building, radio-metallurgical & radiochemistry laboratories, active control fuel assembly
building, free stack (100m) and ventilation stacks
(75 m & 65 m tall). The reactor wall and dome were
of prestressed concrete construction requiring
high accuracy. Another salient feature of MAPP
is the double containment wall with outer random
rubble masonry wall to a height of 34 m, which was
done for the first time in India. ECC has also been
involved in design, installation and commissioning
of 33kV switchyard catering to the entire power
requirement of the Reactor Research Centre at
Kalpakkam. Subsequently electrical installations
for the two research laboratories – RCL & MDL
were done by ECC.
NPCIL once again demonstrated its confidence in
L&T by awarding the complete civil works for Units
1 & 2 of Kaiga Atomic Power Project. Kaiga was
literally a greenfield project necessitating, in many
cases, even basic infrastructure development. The
site was a natural bowl-shaped terrain surrounded
by hills with deep lush green forest and the site
was accessible in fair weather through a forest
road and access to the site was difficult during
monsoon till all the access roads were ready.
ECC’s scope of work included construction of
reactor, turbine, service, control, reactor auxiliary,
diesel generator, spent fuel buildings, 140m high
ventilation stack, area drainage, excavation, area
grading and miscellaneous structures. During
execution of main civil works, ECC was awarded
additional works such as construction of circulating
water pump houses, safety related pump house,
fire water pump house, de-mineralisation, filtration
and chlorination plants, make-up water pretreatment facilities, CW Intake structures and
tunnel, domestic water tank, approach channel
to intake structures and outdoor & indoor piping
works.
Some of the advanced construction methods
used at Kaiga site included climbing formwork
system for prestressed containment walls,
slipform for ventilation stack and formwork for
other structures. A special formwork supporting
structure was designed to support the formwork
of inner containment dome of the reactor.
Construction of Kaiga nuclear power project was
highly challenging, considering the remoteness of
the site, unfriendly weather conditions and other
complexities. Despite the hardships, ECC met the
challenges and successfully completed the project
as per the requirements of NPCIL.
L&T is proud of its association with NPCIL, which
has celebrated its Golden Jubilee Year and wishes
to continue its commitment and contribution for
the development of Nuclear Power Generation in
India.

Tarapur Atomic Power Station
The Tarapur nuclear power station houses two
200 MW Boiling Water Reactors (BWRs). The new
series of 540 MWe nuclear reactors are developed
indegeneously from 220 MWe Pressurized Heavy
Water Reactors (PHWR). At present, this power
station has the largest nuclear power reactor in the
country. It was commissioned seven months ahead
of schedule by the Nuclear Power Corporation of
India.
BARC Installations, Tarapur
The Bhabha Atomic Research Centre (BARC) India’s primary nuclear research facility supports
India’s nuclear power and research programme.
BARC’s installations at Tarapur support the
operations of Tarapur Atomic Power Station.
L&T’s Role
L&T has executed the 2 × 540 MWe at Tarapur
and was involved in almost all the disciplines of
engineering of a Nuclear Power Project. L&T
was involved in main plant civil works, service
water system, reactor piping, composite chilled
water and HVAC packages, electrical works and
instrumentation works – which demonstrated the
capability of L&T in broad spectrum engineering
construction. The heavy engineering division of
L&T had supplied the calandria, steam genertaors
while the Engineering & Construction division
supplied the Primary Steam Piping system. ECC
involved in the mechanical erection of these
structures.
The scope of main civil works package covered
construction of reactor, service, station auxiliary,
reactor auxiliary, control buildings, pipe & cable
bridges, ventilation stack, potable water tank,
roads, site grading, fabrication & structural steel
erection, EPs and other miscellaneous structures.
The gestation period for nuclear power projects
today is considerably reduced by commissioning
TAPP 3 & 4 in 60 months. This is an international
benchmark achievement. At TAPP 3&4, the
challenge of completing the total project in 60
months was achieved by deploying innovative
construction methods. Some of them include
pumping of heavy concrete, casting of 7m
high columns in single lift, use of self climbing
formwork for inner containment wall, casting of 3.5
m high wall for OC wall, prefabrication of calandria
vault liner, use of threaded coupler for reducing
reinforcement congestion and wastage, easy
handling etc.
Design, procurement and construction of service
water system, composite chilled water and
HVAC packages include supply of some critical
equipment such as vertical turbine pumps to work

The primary piping package executed by ECC
(in association with E&C division of L&T) at TAPP
3&4 is meant for nuclear steam supply system
(NSSS) which consists of reactor assembly, the
moderator system and the primary heat transfer
system. The reactor assembly system is the
most important part of NSSS and it consists of
calandria, end shields, calandria tubes, coolant
tubes, end fittings, fuel bundles and reactivity
control devices. The fabrication and erection of
primary piping system is to be carried out in dust
free environment. Extreme care need to be taken
for maintaining clean room conditions not only in
the fabrication stage, but also during erection.
The order for electrical and instrumentation works
is probably the single largest order awarded to
any contractor by NPCIL. These packages involve
design, manufacture, supply, erection, testing and
commissioning of various critical electrical and
field instrumentation items required for a nuclear
power plant.
Fresh Orders from BARC, Tarapur
On completion of the major works at Tarapur,
ECC was entrusted with construction of Additional

Nuclear Reactor Containment
Test Model 1:4 Scaled Pre-stressed
Concrete Containment
B.Sundaramoorthy,
Project Manager
The main objective of the test model is to find out
the behaviour of the Nuclear reactor’s containment
structure under extreme pressure conditions. The
model is pressurized three times more than the
actual design pressure of the Nuclear Reactor.
The model is also tested to establish and check
the design parameters of the actual containment
structures and to get better understanding of
structural behaviour of the containment structure
for future.
Test Model at Tarapur
The pre-stressed concrete containment test model
is scaled down to represent the actual Pressurised
Heavy Water Reactor of Tarapur Atomic Power
station 3 & 4 at Tarapur, to a factor of 1:4. This
model is constructed at Tarapur close to the
existing BARC facilities.
Contented by the performance of L&T in Tarapur
Atomic Power Project 3&4, NPCIL invited L&T to
construct the model on nomination basis.
After the construction of the model, the same will
be subjected to a pressure, which is approximately
4.5 to 6 kg/sq.cm or even higher. However, the
actual failure pressure will be established after
testing. In any case, it is expected that there will
be nominal leakage at 5 kg/sq.cm.
Salient features
All the components of the actual reactor is scaled
down to 1:4 including pre-stressing, critical
openings etc.
Raft
The inner containment wall is supported on a raft
having dimensions of:
•
Diameter -15.60 m and
•
Depth of 3 m
•

Inner Containment Dome (IC Dome)
Construction Joints-Fuko System
The IC dome starts at 13.706 m height and springs
up to the crown 15.750m.
Construction joints in the dome and the inner
containment wall were sealed using Fuko system
i.e. Re-injectable grouting system with injection of
hydro swelling, water based, low viscous, thermosetting resin. This is done after construction to
make the joint leak tight for air and water.

•
Inner containment dome was cast in single
pour
Challenges
The work involved several challenges like:
•
Placement of reinforcement, HDPE sheaths
and tube units, due to congestion in scaled
down thickness of walls and dome having
stringent tolerances of +/- 3 mm.
To monitor the response during prestressing of
containment and dome, following sensors were
used:
•
Installation and protection of 727 sensors in IC wall and dome during preparation of pours
and concreting were tough tasks
•
727 sensors were installed in concrete
from raft to crown of the dome at
pre-determined locations
•
Utmost care was taken during installation
and 99% of sensors are functioning well even
today.
•
89 sensors were installed on HT strands and stressing was analysed
•
Different type of sensors used in test containment
included:
Installation of instruments in wall and dome
due to slender section i.e. 188 mm thick of
wall and 164 mm thick of dome.
•
Formwork •
Embedded type of Vibrating Wire Strain
Gauge(VWSG)
- Nuts were not allowed through ties and coil
- Slender sections
•
Pastable SMER 10 mm
•
Spot weldable 51 mm, Weldable 203 mm and
•
Earth pressure cell
- Complicated tailor made formwork system
was used with prefabricated “C” shaped MS
frames
•
Difficulty in mounting large number of
instruments in limited space around openings
of Airlock Barrels.
Sensors
Weldable type of sensors were installed on
reinforcement bars whereas embedded type in
concrete.
Pre-stressing
Inner containment wall and dome was subjected
to prestressing using prestressing system 1T15.
This involved:
•
Total number of 313 cables, comprising of
JO & JI, Vertical and Horizontal cables.
•
15.2 mm diameter high tensile strand for prestressing works
•
HDPE sheathing of 25mm-OD/20mm-ID.
•

21.20 t on each cable and
•
Sheathing was cement grouted
temperature controlled cement grout
with
Efforts required for the construction of the test
model involved same amount of work or more
than that required for the proto-type due to the
limitation in scaled down dimensions.
Health Safety and
Environment
Regular training and orientation programs for
workmen were conducted to keep them alert at all
times.

Kudankulam Nuclear
Power Project
A.U. Rao
Planning Manager
N.P. Varadharajan & R. Balasubramanian, Project Managers
I
ndia’s first 2 × 1000 MWe Nuclear power plant
is coming up at Kudankulam. The project is
located on the shores of Gulf of Mannar, on the
Southeastern tip of India near Kanyakumari. It is
located at Radhapuram taluk of Tirunelveli district
in Tamilnadu state.
The site experiences a tropical climate with
humidity ranging from 40% to 90% depending on
the season and is subjected mainly to the winter
monsoon during the months of October, November
and December.
The Kudankulam Nuclear Power Project (KKNPP)
consists of two units of 1000 MWe with two steam
driven turbo generators supplied with turbine
steam from two pressurized water VVER type
reactors of Russian design. The design of various
equipment, systems and structures are carried out
in accordance with Russian and other International
Standards.
The entire project capacity of 2000 MWe (2 x 1000
MWe) of power will be supplied to three southern
states (Tamil Nadu, Karnataka and Kerala) and the
Union Territory of Pondicherry. NPCIL has divided
the whole project into number of packages and
awarded to different contractors. The whole project
cost is about Rs. 13,000 cr.
Packages
L&T has been awarded M2, M4, M5, C5 and E1
packages directly by NPCIL. M3 and I1 have been

Technical Aspects
Kudankulam Reactors are Water-cooled Water
moderated Energy Reactor (VVER-1000) of
Pressurized Water Reactor (PWR) technology,
which is worldwide proven concept. VVER-1000
reactors are the most advanced reactors
similar to the PWR’s of western design. Nuclear
fuel is charged into the reactor where the fission
takes place and the heat is liberated. The
liberated heat in the reactor is carried away by the
light water from the reactor to steam generator
by the main coolant pump. De Mineralized
(DM) water acts as reactor coolant. The coolant
water is used in the steam generators to produce
steam. The steam is allowed to pass through
turbine blades with high pressure and velocity.
The turbine then rotates receiving the kinetic
energy of the steam. The generator, which is
mechanically, coupled to the turbine also rotates
and generates power. The back steam of the
turbine is allowed to pass through the surface
type condensers. The condenser will be having
tubes through which sea water is allowed
to flow and over which the steam flows. The
sea water absorbs the heat from the steam and
condenses the back steam. The condensate is
recycled back to steam generator. The sea water
after absorbing the heat from the back steam
is discharged into sea and fresh water is drawn
through inlet.
Erection of Reactor
Pressure Vessel in

Mechanical works for India’s Largest Nuclear
Power Plant
Larsen & Toubro has won all major mechanical
erection and installation. This includes four
mechanical packages and two electrical and
instrumentation packages.
The scope of work in M2 package include handling,
transportation, pre-fabrication, welding, erection,
inspection & testing of piping, instrument tubing
and erection of associated equipment along with
accessories for nuclear steam supply systems and
nuclear auxiliary systems for Unit 1 & 2. This main
mechanical package involves heavy erection of
critical nuclear equipment like Reactor Pressure
Vessel, Steam Generators, Reactor Cooling
Pumps, associated piping in reactor and auxiliary
buildings, various safety systems like boron
injection system, passive heat removal system
and containment sprinkler system.
Erection and alignment
of NSSS Equipment
In this M2 package, reactor equipment (2 x 316 t
each) was erected in four stages. Being a nuclear
project, high degree tolerances limit (0.01mm) was
maintained. Another challenge during the erection
was the clearance between the inner diameter of
support structure and outer diameter of Reactor
Pressure Vessel (RPV), which is only 10 mm and
large volume of blue matching.
Steam Generator (8 x 307 t each) was erected in a
confined space with the alignment in the range of
0.4 mm to 0.5 mm.
Pressurizer (2 x 222 t each) was also erected in
confined walls with the tolerance of 8mm w.r.t containment wall and alignment in the range of
0.4 mm to 0.5 mm.
All the above erections were executed using highly
precision optical tooling survey instruments viz.,
Jig Transit.

System Description
The electrical system for the two units of
Kudankulam nuclear power plant, each of 1000
MW, mainly consists of power output system and
auxiliary power supply system. The power output
system is designed for evacuation of power
generated at NPP. The auxiliary power system
provides the power to NPP auxiliaries to carry out
their assigned functions, in all operating modes of
NPP.
Power Output System
The electrical power generated by the turbine
generators at 24 kV, three phase and 50Hz is
stepped up to 400 kV by the generator transformer
and is evacuated through four 400 kV transmission
lines. For reserve source of power to auxiliaries of
NPP, Kudankulam NPP is connected to Tuticorn,
SR Pudur and Kayathar through 230 kV lines.
400 kV and 230 kV lines are connected through
interconnecting transformers. 400 kV and 230 kV
switchgear are of SF6 gas insulated considering
the saline atmosphere at Kudankulam site. 400 kV
is designed as one and half bus scheme. 230 kV is
designed as two main bus schemes.
Major components of the power output system for
KKNPP include:
• 24 kV 1000MW generator
• 24 kV 31.5KA Isolated Phase Bus duct (IPDB)
• 24 kV 28KA generator circuit breaker (GCB)
• 3 X 417 MVA, 24/400kV generator transformer
(GT)
• 400 kV 2000A gas insulated bus duct (GIDB)
• 400 kV gas insulated switchgear (GIS)
• 400 kV transmission lines
• 315 MVA, 400 kV /230 kV interconnecting
transformer (ICT)
• 230 kV gas insulated switchgear (GIS)
• 230 kV transmission lines
• 1 phase 26.7 MVA shunt reactors (6nos)
Auxiliary Power Supply System
The main function of the auxiliary power system is to
ensure the availability of sufficient power supply to
the auxiliary system equipments during all modes
of plant operation i.e. normal plant operation,
shutting down the reactor, maintaining the reactor
in safe shut-down state, containment isolation,
reactor core cooling, preventing significant release
of radioactive material to the environment and any
other necessary functions.
For start up as well as for normal shutdown of both
units of plant, station auxiliary power is drawn from
the 400kV network through generator transformer
and unit auxiliary transformers with the GCB
open.
During normal plant operation, station auxiliary
power is drawn from the main generator from the
tap-off to 24kV bus duct through the UATS.
The reserve power supply is derived from 230kV
grid through 230/6.3-6.3kV RATS and is used as
backup power during non-availability of power
supply from UATS.
The common station auxiliary power supply feeding
the common station auxiliary loads is derived from
230kV grid through 230kV/6.3-6.3kV CSATS and is
backed up by the RATS.
The system mainly consists of 6kV, 0.38kV and
220 V DC power supply sources to supply to
unit auxiliary loads and common station auxiliary
loads.
Auxiliary power supply system envisaged for
KKNPP is categorized as per their functional
requirements detailed below.
• Normal auxiliary power supply for each unit
system including common station auxiliary
supply system for the plant.
• Reliable auxiliary power supply of normal
operation for each plant.
• Emergency auxiliary power supplies system
for safety systems for each unit.

supply.
These are fed from 6kV, 380V and 220 V AC, 50Hz
supply derived from UATS, RATS or CSAT.
Principles of Control, Monitoring and
Relay Protection System
During operation, a system is understood as a
set of devices of relay protection, control and
monitoring of the electrical equipment, structurally
and functionally involved. At KudanKulam NPP,
independent system of control, monitoring and
relay protection system are provided for many of
the systems.
Gas Insulated Substation
Here switchgear apparatus for 220kV and 400kV
equipment use the SF6 as dielectric media due to
many of its advantages.
• Though SF6 was developed in 1900, it was
used as dielectric medium only after 1940
• It is a powerful dielectric medium
• Its dielectric strength is 2.35 times to that of air
• It is 5 times heavier than air
• It is non-toxic in pure form
• Its dielectric strength is proportional to the
pressure that it operates
• This is well suited for HV switchgears and GIS.
The gas passing through the isolated bus duct acts
as a powerful insulation media and this compacts
the size of the switchgear.
Grounding and Lightning Protection
To achieve the requirements, a grid consisting of
70 sq.mm tinned stranded copper conductor has
been laid by the civil contractors at a depth of not
less than 0.5 m below the foundation, with a mesh
size of 25m × 25m in the outdoor area and about
6m × 6m mesh size beneath the buildings. GI
earthing conductors run to walls and floors inside
the buildings, which form the main grounding lines
are connected to the buried copper conductors.
All the metal components inside the building are
connected to the grounding network.
220 kV gas insulated
substation
Lightning protection conductors in a mesh
formation are provided over the building surface,
along outer perimeter walls and on the roof and
are connected to the grounding grid. Lightning
arresters are installed on the stack top.

ECC Concord | Jan - Mar 2009 26
85 lakh cu.m of earthwork excavation and
10 lakh cu.m of embankment. The soils met with
on the course of the alignment were generally red
earth and hard gravel.
The depth of earthwork excavation in normal
section ranges from 5-7 m depending upon the
ground level. A 40 m deep cut hard rock excavation
at flumed section is one of the most critical and
adventurous one.
Lining of Main Canal
Profile Walls shall be laid at 8.75m and 17.5 m
intervals in curve portion and straight portion
respectively for formation of Subgrade before
laying the Lining Concrete. More than 600 workmen
were deployed for Subgrade preparation. In
addition, Graders and Rollers were also deployed
for formation of Subgrade.
The lining for the main canal was done with M10
grade of concrete with 40mm maximum size of
aggregates. 100mm thick lining concrete was laid
for the entire bed width of 73.25m with slopes on
both sides up to a height of 4.95m from the canal.
On the whole the work involved 1.8 lakh cu.m of
lining concrete.
Contraction Joints at 5m intervals were provided
in both transverse and longitudinal direction.
This apart, suitable construction joints, concrete
sleepers, transverse drains, longitudinal drains,
porous plugs were also provided in lining
Concrete.
Cross Masonry &
Cross Drainage Structures
A number of streams and small village roads cut
across the main canal at different locations. To
provide access to the villagers as well as to allow
the streams to pass across the main canal for
irrigation facilities etc., different types of structures
were proposed in the alignment of the main canal.
Thus, 24 different structures were constructed
in the canal alignment for meeting various
requirements.

indal Power Limited, a leading power generation
company, and a subsidiary of Jindal Steel has
set up a 1,000 MW super thermal power plant at
Tamnar in Raigarh district, of Chhattisgarh. For the
consumptive water use in the power plant, a dam
has been built across river Kurket, near village
Rabo, which is about 33 km from the power plant.
This 200 m long 18.5m high dam supplies about
40 cu.m per minute of water to the power plant
and meet the consumptive and circulating
requirements of the power plant.
Apart from being the full fledged dam project
undertaken by ECC, this unique and landmark
project was fraught with several social and
environmental problems.
Braving all the odds, L&T successfully completed
the project and the flood gates were formally
opened and inaugurated by Mr. Saraff, President
– Jindal Power Limited on July 13, 2007.
Salient features
• Main earthen dam in the Riverbed - 200m
long, 18.5m maximum height

Remote Location
As the site was located at 35 km from Raigarh,
a 11km approach road to site was strengthened
before commencement of the work. In addition,
L&T had to establish V-sat connection as there
were no communication networks available in the
vicinity.
Diaphragm wall
Initially, the diaphragm wall for the main dam was
an RCC structure. After the work was awarded,
the consultant changed the structure from a rigid
D-wall to a flexible D-wall using plastic concrete
and doing away with the reinforcement. The
Foundation Engineering Competency Cell of ECC
took this challenge and developed a new design
mix for this type of plastic concrete. The formula
worked perfectly and the work was executed
successfully.
Achievements
Major portion of project excavation for spillway,
concrete for spillway, fabrication, erection &
commissioning of spillway gates and earthen dam
in the river portion including rip-rap works, were
completed in the stipulated time of 25 months
and handed over to clients. This project received
Prashansha Patra from National Safety Council
of India – (Safety Awards – 2007) for achieving 4
million safe man-hours without any lost time due
to injury. Site also received Annual Quality trophy.

rid landscapes, barren fields and dusty track
lands define the upland areas of Prakasam,
Nellore and Kadapa Districts in the State of Andhra
Pradesh, which fall under the severe drought
prone zone. With the completion of four ongoing
irrigation projects – Veligonda, Gundlakamma,
Ramatheertham and Palair, the scenario is
changing. These four projects increased the
irrigation potential of this region from the present
7.45 lakh acres (3.01 lakh hectares) to 13.45 lakh
acres (5.44 lakh hectares) in a couple of years.
This quantum jump of 80 per cent will be achieved
after the completion of Rs.4000 crore projects
under the “Jalayagnam” programme.
A huge reservoir, called the Nallamala Sagar,
is being formed and three dams are being
constructed at Gottipadia, Sunkesula and Kakarla.
Water is drawn from Kollamvagu foreshore on
right bank of Srisailam reservoir through 18.80 km
long tunnel by gravity and thereafter diverted to
Nallamala sagar through a 23.36km feeder canal.
The canals are proposed from Sunkesula gap,
Gottipadia gap and Kakarla gap and envisages to
draw 43.50 TMC of flood water from river Krishna
upstream of Srisailam reservoir to irrigate 4.38 lakh
acres (1.7 lakh hectares) in 29 mandals, mostly in
Prakasam district and marginally in Nellore and
Kadapa districts.
L&T is entrusted with the construction of one of
these dream irrigation projects – The Veligonda
Dam. The project will provide irrigation benefits
to upland areas of the district besides providing
safe drinking water to 15 lakh people, who have
been consuming groundwater with excess fluoride
content for decades. L&T’s scope of works
comprise construction of dam at Gothipadia
and excavation of Gottipadia Canal including
construction of cross masonry and cross drainage
works, distributory system for 9500 acres. L&T
secured this contract in 2005 from Irrigation &
Command Area Development Department of
Andhra Pradesh against stiff competition.
Valued at Rs. 395 crore, this is the first major
concrete dam project executed by L&T on an EPC
(Engineering, Procurement and Construction)
basis. The scheme comprises construction of
dam from EL 162 to EL 230 having a base width of
57.96m and top width of 12m, canal length 11.40
km and distributory system for 9500 acres.
Salient Features
• Height of the dam from the deepest
level - 87m
• Total length of the dam at the top - 600m
• Slope of the downstream face- 1 : 0.662
• Slope of the upstream face - 1 : 0.045
ECC’s major scope of work includes 10,00,000
cu.m of excavation, 9,21,181 cu.m and 1,00,000
cu.m of concreting in two stages, 1600 t of
reinforcement, 2,30,000 sq.m of formwork, 58,000
Rmt drilling for grouting, 51,000 cement bags for
grouting.
Concreting
• Total concreting is 10,21,181 cu.m in two
stages
• Total duration of concrete pouring
24 months
• Average rate of concrete pouring achieved
1500 cu.m perday
• Peak rate of concrete pouring achieved
2903 cu.m per day
The project had a huge requirement of concrete,
which was to be poured at a temperature of 15
degree celsius. The herculean task of achieving
and maintaining the standard of concreting was
managed with meticulous planning. As the height
of dam started increasing, earthen ramps up to
30m height was created for the movement of
concrete. Later, conveyor was used for shifting
concrete from the batching plant to the top. As
the project required steel formwork, the entire
shuttering was designed and schemed in-house
at site. Hydra cranes were used for handling the
forms. To reduce the cycle time, the shutters
were combined (4.8 m combined width) with
structural steel channels. The whole sequence
of operations, from aggregate production to
concreting was mechanized thereby ensuring
accuracy and maximum output.
The client
awarded commendation certificates for the highest
concreting (46000 cu.m) in the month of February
2006.

Engineering Challenges
Resources
Veligonda dam project is the first dam project
designed by the Engineering Design and Research
Centre (EDRC). EDRC looked at the opportunity
as a challenge and successfully completed the
design of concrete dam. The internal arrangements
within the dam body like gallery, adit, shaft, and lift
were designed with precision. The dam consists of
around 2 km of gallery within it for inspection and
grouting. Planning and aligning this multi level
gallery and the interconnection of the galleries
with access adits were really brain racking. Like in
any other dam, ‘A’ holes and ‘B’ holes for grouting
were designed to improve the impermeability of
dam base. The dam base was grouted with a
total drill length of around 22 km. Different types
of instruments were embedded in dam body to
monitor the dam in terms of settlement, plumb
and thermal. The monitoring was reviewed with a
computerized data acquisition system.
Remoteness of the project posed the biggest
challenge as management of materials was
a critical task. Except for the aggregates, the
minimum distance for sourcing of other materials
was around 200 km away from project site.
Interacting with the vendors and convincing them
to deliver as per the schedule was one of the most
critical activity for the smooth progress of the
project.
• Vol. No. 31 • Issue No. 4
ECC Concord | Jan - Mar 2009 32
Sourcing of aggregates was another major issue.
Markapur is famous for slate rock formation
which cannot be used as aggregates because
of its hard and soft rock combination. The site
has established a rapport with a local quarry for
uninterrupted supply of aggregates.
Identifying and sourcing the total requirement of
boulders (22 lakh mtp), was a major issue during
the initial phase as the local terrain had affinity
to slate rock. Two crushers with a combined
capacity of 450 tph are installed to cater to the
aggregate production. Sand impactors are used
to enhance the quality of the aggregate output.
This mechanized system of aggregate operations
was instrumental to achieve the planned output.
Sourcing of river sand also was a challenging task
as the nearest supplier was around 220 km away
from project site.
Plant & Machinery
The initial review of similar dam sites was
instrumental in planning the machinery
requirement for the project. The methodology
involved in concreting was through dump trucks,
transit mixers and tower cranes. Two 125 tpd
chilling plants, 250t of refrigeration, two ice plants
were installed for getting the required concrete
pour. During summer, the temperature crossed 50
degree celsius and maintaining concrete pour at
15 degree celsius was the most critical challenge
through out the execution.
Specialized major P&M deployed include
120 cu.m/hr concrete batching plants with
aggregate individual weighing system for the best
accuracy.
Quality and Safety
The project site followed the norms of ISO 9000
and has been reviewed by various audit systems
at regular intervals. Safe methodology was
incorporated in all activities of the project. Daily
pep talks and regular orientation programmes
ensured the communication of safety issues
and awareness is created down the line across
various departments. A system of automated
house keeping was implemented, where before
commencement of work, the workmen ensure
appropriate environment is maintained.
Some of the safe methods employed at sites
included three lockwork permit systems for
rotating parts, cordless communication system for
tower cranes, and sensor alarm in hydra cranes.
Innovations
Innovations and in-house alternatives are the
hallmarks to the speedy execution of this project.
Buckets of 3 cu.m capacity for concreting and
vibrator needles were locally fabricated which
resulted in considerable saving of time. Gantry
for handling of Formwork was designed by
Construction Methods and Planning Cell (CMPC).
CSR
As part of the corporate social responsibility, two
additional class rooms for the local government
school was built by L&T. An environment friendly
zone is being nurtured at the project site. About
892 saplings were planted during HHL Centenary
Celebrations. Three more class rooms were
constructed for the Government school at
Kaolabhimanipadu village.
The project team maintained cordial relationships
with the locale population, which was instrumental
in the smooth flow of work. Veligonda Project
contributed to reconstruct a temple which had to
be relocated due to the dam construction.

During the programme, Mr. Richard interestingly
explained the process and methodology with many
case studies and insisted the need for a thorough
knowledge, common sense and presence of mind
for safe execution of the Heavy Lifts. At the end
of the programme, a test was also conducted
to evaluate the learning of every participant and
certificates for the independent assessment were
e-mailed.
Mr. K.P. Raghavan, EVP & Head – Divisional

Project GreenHands for saving the nature
and creating a better future
F
or the last seven decades, L&T has been
addressing the needs of communities and
taking initiatives in the areas of health, education
and community development. On April 9, 2009,
the Construction Division of L&T made a humble
beginning and a major green initiative to save our
Mother Earth.
L&T has resolved to grow 50,000 saplings in the
next 18 months and plant it in different projects in
and around Chennai. As a first step, a nursery was
set up to grow 10,000 saplings in the first phase.
This initiative was kick-started in the evening on
April 9, 2009 by Mr. K.V. Rangaswami (KVR),
Member of the Board and President (Construction),
L&T by planting the first seed in the mother bed.
The guests and the audience were thrilled with
the venue of the function as it was conducted
under the shade of trees, which is one of the many
benefits of a tree. To the delight of everyone, the
chief guest and senior colleagues were welcomed
with the saplings instead of bouquet. Impressed
with this idea, KVR requested to follow this practice
in all future functions.
Welcoming the guests, volunteers and the
audience, Mr. V.S. Ramana, Head – Corporate
Communications highlighted the fact that though
we come from suburbs, over the generations,
we have become city bred people and lost the
connectivity with greening, plants, saplings and the
earth. To get back and reconnect with this link, he
said that, ECC has taken concrete steps to initiate
“Project GreenHands”, in collaboration with Isha
Foundation. He stated that, “As a construction
company, L&T perhaps gets perceived as builders
of concrete jungle. But it is not true of the
company’s image; rather the company has a lot of
passion for greenery.”

Mr. Ashraf, a volunteer from Isha Foundation
elaborated the effects of global warming and how
this kind of initiative to build the green cover help
to prevent the nation from disasters.
Mr. S. Kanappan, Vice President & Head – EDRC
(B&F OC) in his speech focused on how ECC
is contributing to the Green Concept by way
of planting 10 trees for every one tree cut down
during construction. He brought to notice the
water consumption on campus and how this water
is treated for irrigation of the trees and added
that, “Today efforts are being made in order to
reduce carbon emission from power plants and
buildings because of the threats that environment
is facing.”
Mr. R.C. Swamy, Vice President and Chennai
Center Head for L&T Infotech spoke about the
various activities of “Vidiyal” - a Special Interest
Group, concentrating on Infotech’s CSR activities.
He also urged everybody to do their part in
effective waste disposal by reducing, segregating
and reusing waste materials.
Mr. Rangaswami in his speech said “The
phenomenon of global warming is something
which is real, not a distant future, but in the
foreseeable future. Today the whole country is
going through a movement of road building which
is very much required, and we are ourselves
engaged in 20 and odd projects, and one of the
main aspects of road building project is cutting
tree, but as a part of one of our projects in Gujarat,
some millions of trees had to be planted! So the
government knows that it has to be done. We also
know, for the development of our campus some
trees have to go, but we had to ensure that the
number of trees (cut) is restricted to the minimum,
and an equally important initiative is building up
(the green cover), I say if one tree is cut, at least
20 trees must be planted, that is the ratio I would
like to give.”

audience
This memorable function was concluded with a
vote of thanks from Mr. B. Ramakrishnan, Vice
President (Finance, Accounts & Admn.), Divisional
Corporate.
Green Camps
O
n Sundary, April 5, 2009, around 40 L&Tites joined together to visit a nursery run by
Isha Foundation in Kodungaiyur at the outskirts of
Chennai. Entering the nursery, the group saw a
big table with varieties of saplings titled in Tamil
and English. Soon they were explained about
the various timber, fruit, flowering and fodder
species. The special characteristics of the trees
like the medicinal properties of neem, the rain
making capacity of the thoongu vaagai, the Ozone
generating properties of the Arasan (peepal)
and the fact that the monetary value generated
by a fifteen year old peepal tree is around 10-12
lakhs per year, were all astounding and thought
provoking.
Followed by the orientation, the experts from Isha
Foundation demonstrated the sand-manure mix

While filling the packets with sand-manure, the
team was engaged in enchanting music and
during the break with energy-bursting games.
Sitting under the shade of a single large mango
tree, the team thoroughly enjoyed the activity
and completed 1200 packets. The single large
tree gave enormous comfort to the team in spite
of Chennai’s typical hot and humid climate. At
the end of the day, the team finished the work by
moving the mud filled packets to another place
near the mother bed by forming human-chain. In
the experience sharing session at the end of the
day, everybody expressed their joy of spending
meaningful time during the holiday.
After learning the tricks of the trade in the first
camp, another team of 40 people participated
in the second camp at L&T Nursery on April 19,
2009. All the participants enjoyed their time and
were immensely satisfied for their contribution.
The third camp was unique as it was celebrated
on May 1st as initiation day of L&T. May 1, 1938,

a humble beginning, L&T has over the years
become a giant in India’s Corporate Sector, which
offers direct employment to over 40000 people
and indirect employment to about 4 lakhs with 10
million shareholders!
75 people comprising men, women and kids
participated in the nursery activity in the full
morning session. During the break, they took part
in games, which took them back to their younger
days. After sharing their experience and narrating
the touching aspects of the green initiative and
concept, they enjoyed the music, mimicry and
dance performances at the end of the day. It was
a fruitful and fun-filled camp.
As part of the “GreenHands“ campaign, L&T-ites
at Coimbatore Project site have taken the initiative
and planted 100 trees in and around the factory
campus on April 8, 2009. Mr Sarkar, Head of L&T
